I'd go with Northern Lights #5 if it's your first time, relatively small and easy to grow strain that can handle many grow situations. Low temps low humidity low light haha it can thrive under anything and produces A+ smoke even for first timers. Doesn't get big (Indica dom) so that's good for indoors and I can tell you mine didn't smell too bad, so if odor is an issue that's good too. Go with Nirvana through attitude, I did and my genetics are amazing haha.
